Ignore components by name

[posva]

It could be useful to ignore components given a pattern. e.g. src/routes/_not-a-page.vue, or .not-a-page or __not-a-page, etc but at the same time this can be achieved with the exclude option so is this really necessary?

I think it's worth adding a default value to exclude and let users override this if necessary. As for the convention, a file or folder starting with _ seems like an easy choice since URL usually do not start with a _. It still requires the option to be overridden for edge cases:

exclude: [
  '**/_*', // files
  '**/_*/**, // folders
  '!_not-ignored',  // _not-ignored should still be handled
]
